Need some help

I had sexual intercourse on 12/23(took a plan b), 1/1(pull out method), and 1/8(condom). After taking the plan b, I got my period on the 1st of January, and haven’t had it since. I took about 5 pregnancy test since and all were negative, so I decided to take two this morning, before today i’ve tried the 88cent test, first response early detection, and clear blue early detection(all negatives). These are the ones taken this morning.
